In 2.1, the centrifuge sections are no longer separate graphics, making the game unplayable, of course.
This mod makes the centrifuge tintable and also restores the old centrifuge graphics, but with the saturation lowered to look like the 2.1 centrifuge. If you want to tint a centrifuge recipe, you can use crafting_machine_tint but this mod also supports centrifuge_tint specifically for centrifuge tinting, with the following fields:
base= The base color. Also use this if you just want a single color.light= The background light color.top= The top section.left= The left section.right= The right section.
